[Dandy-Walker malformation associated with extracranial abnormalities in a newborn]

Area of Science:

• Pediatric Neurology
• Developmental Biology
• Clinical Genetics

Background:

• Dandy-Walker malformation is a rare congenital brain abnormality often associated with hydrocephalus.
• Hydrocephalus results from cerebrospinal fluid accumulation around the brain.
• This condition necessitates comprehensive evaluation due to potential associated anomalies.

Observation:

• A newborn presented with prenatal diagnosis of hydrocephalus secondary to Dandy-Walker malformation.
• The infant also exhibited ambiguous genitalia, specifically interscrotal hypospadias.
• Coronary sinus dilatation was noted, attributed to persistent left superior vena cava.

Findings:

• Postnatal confirmation of Dandy-Walker malformation with rare extracranial manifestations.
• The case illustrates a complex presentation beyond typical Dandy-Walker findings.
• Associated anomalies significantly impact patient prognosis and management.

Implications:

• Dandy-Walker syndrome complexity underscores the importance of thorough diagnostic workups.
• Associated extracranial malformations necessitate a multidisciplinary treatment approach.
• Early identification and management are crucial for optimizing outcomes in affected neonates.
